Title: Magnetic sludge suitable for waste water treatment and its production and treatment of waste water
Inventor: MAEKAWA TAKAAKI
IPC: C02F3/28
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To improve waste water treating efficiency by using one containing microorganism and having magnetic field reactivity as a magnetic sludge. SOLUTION: This magnetic sludge for waste water treatment contains microorganism and formed so as to have the magnetic field reactivity and if necessary, a paramagnet is incorporated. The magnetic sludge is produced by using a high polymer as a supporting body and capturing and supporting an ultra paramagnet and concentrated sludge on the high polymer. In the case of applying to an upward flow anaerobic sludge bed reactor, a large quantity of the microorganisms are held in the inside part and on the surface of the magnetic sludge in the sludge bed to decompose the organic material or nitrate nitrogen to generate gas. The direction of the magnetic field is periodically changed by mounting magnet coils in >=2 directions to apply magnetic field to the sludge bed from the outside of the device and applying current with the time staggered.  As a result, the sludge bed is moved little by little to accelerate the releasing of the generated gas and to prevent the clogging or the short circuit.
